Ohmite’s TDH resistor is an economi-
cal solution to intermediate power
application design requirements.
TDH’s reliable thick film on alumina
substrate construction can be easily
heat sinked for higher power perfor-
mance. TDH resistors are ideal for
pulse-loading, pre-charge, bleeder,
and snubber applications.

THIS PRODUCT IS DESIGNED FOR
USE WITH PROPER HEATSINKING.
Maximumbaseplatetemperatureoftheresistormust
be monitored and kept within specified limits to es-
tablish the power rating. Best technique is to attach a
thermocouple to the side of the base plate of the resis-
tor. Temperature of plastic housing or heat sink cannot
be used to establish rating of the resistor.
